What Colour would a blue object look in red light?

black
So what happens if you shine only red light onto a blue object? All of that red light gets absorbed and the blue object will seem to be dark, almost black.

What color does a blue book appear when illuminated by only red light?

This occurs because the blue book absorbs all the red, leaving nothing to be reflected, so it appears black. White light is made up of all the different colors (wavelengths) of visible light.

What Happens When blue light hits a red object?

So when blue light is allowed through a blue filter onto a blue object, the object will still reflect blue and therefore appear blue. But when blue light from a blue filter hits a red object, the blue will be absorbed and no light will be reflected, giving the object an appearance of being black.

Does a blue object absorb red light?

A blue pigment is capable of absorbing yellow light. That is, blue paper can absorb both red and green primary colors of light (recall that yellow light is a mixture of red and green light).

Do blue objects absorb blue light?

A blue object absorbs all wavelengths of light but blue. So when blue light is shined onto a blue object, all of the blue light is reflected back. This makes the blue object look blue as always.

Why do blue objects appear blue in sunlight?

Objects that appear blue do so because they reflect blue light but absorb all other colors, so our eyes only see the blue light remaining. That’s probably why we evolved to see the colors that we do – because the sun puts out most of its energy in that part of the electromagnetic spectrum.

What colors does black reflect?

1. Black is not a color; a black object absorbs all the colors of the visible spectrum and reflects none of them to the eyes. The grey area about black: A black object may look black, but, technically, it may still be reflecting some light.

Why does a blue object look blue in sunlight?

Objects that appear blue do so because they reflect blue light but absorb all other colors, so our eyes only see the blue light remaining. When a blue object absorbs the energy from non-blue light, it heats up.

Does red absorb light?

If the color of a surface is anything other than white, it means that it absorbs light of some wavelengths. For example, a surface that appears red absorbs yellow, green, blue and violet light, while reflecting red light. Black is the least reflective color, it’s the color of a surface that absorbs all light.

What color is reflected by red?

If the color of a surface is anything other than white, it means that it absorbs light of some wavelengths. For example, a surface that appears red absorbs yellow, green, blue and violet light, while reflecting red light. A surface that appears green absorbs all colors except green.
